Exciting new preprint from my dear colleague Camille! It's been inspiring to see all the hard work and passion she poured into it. Congratulations! 🦋

Transposable elements underlie chromosomal fusions and fissions in a highly species-rich group of butterflies https://www.biorxiv.org/content/10.64898/2026.06.15.732387v1

Really great to see this preprint out! Amazing effort by @camillecornet.bsky.social, and a privilege to have been involved in this one, thanks for beginning me back to butterflies, Camille! 😉 #TEsky #TEworldwide #Genomics #Bioinformatics #Chromosome #Evolution #Butterflies

🧬🦋 New preprint out! 🦋🧬 What mechanisms underlie large-scale chromosomal rearrangements? Why do rearrangement rates vary so massively across taxa? We explored these questions in Erebia butterflies, a genus with extraordinary chromosome number diversity, from 7 to 52! www.biorxiv.org/content/10.6...

Latest paper lead by Asia Hoile with @peterhox.bsky.social is out! 🦋 Nymphalid butterflies have reduced forelegs. Gene expression patterns show support for more palp-like genes involved in sensory processes in the forelegs relative to the walking legs. doi.org/10.1111/imb....

Sloths are the slowest mammals on the planet and now we know why. Scientists have sequenced the two-toed sloth genome and found ‘jumping genes’ linked to their extremely slow metabolism 🦥 Read more here ⤵️ https://www.sanger.ac.uk/news_item/why-are-sloths-so-slow-its-in-their-dna/

A big preprint from my group! Muller Elements are considered to be conserved in flies. We tested it by reconstructing the ancestral dipteran karyotype using 340 chromosomal genomes and suprise suprise, they're not... Led by @juliagries.bsky.social and Sam Ebdon. www.biorxiv.org/content/10.6... 🧵👇

@eksramos.bsky.social et al. reveal that the marine transition in turtles is characterized by rapid evolution and expansion of genes linked to iron metabolism, organ morphogenesis, sensory perception, mirroring other secondarily marine tetrapods. 🔗 doi.org/10.1093/molbev/msag114 #evobio #molbio

This Wednesday! Looking forward to hearing more about @aruizherrera.bsky.social 's research. 🧬

When you zoom out from individual genes to consider the context of whole chromosomes across animal diversity, animal evolution takes on a different look. Oleg Simakov and I published a review in @annualreviews.bsky.social on topological approaches in comparative genomics. 🧬 doi.org/10.1146/annu...

Chromosomes are often classified as either monocentric (single centromere per chr) or holocentric (centromeric activity spread across each chr). In reality, there is a continuum in centromere organisation - and cyperids are a fascinating system to explore this in as James shows in this preprint! 🌱

Why do the chromosomes of cyperids (sedges & rushes) split and fuse so regularly on evolutionary timescales? Is it because they have so many centromeres? Our new preprint, the first major paper of my PhD, addresses this question. 🧵⬇️ 1/12 www.biorxiv.org/content/10.6...

Now online! In this review, we cover four major topics on butterflies and moths: their evolutionary history and diversification dynamics, genomics, global diversity patterns, and conservation 🦋🌏 (1/8) @natrevbiodiv.nature.com www.nature.com/articles/s44...

Hi everyone! The talk I had the chance to give with @fnucleosome.bsky.social last October is now out on Youtube! If you like evolution, 3D genomics, biodiversity and/or fungi, I think you might like it! 🧬🧪🍄 The submission of this paper has never been that close! www.youtube.com/watch?v=Plez...

We hope this little guide and review of the recent literature on SVs will be useful for the community in #ecology #evolution #genomics #PopGen. Great lead by Kat!!

Very excited to share that my first first-author pre-print is out today! Many thanks go out to all of our collaborators, especially those who helped with the fieldwork in Peru - it really wouldn't have been possible without you! 🦋

📢 Three new #bioRxiv preprints from our team on holocentric chromosomes. Together, they connect centromere repeat evolution, karyotype dynamics, and meiotic recombination outcomes, revealing how holocentric genomes evolve and function. 🧬👇

🦋🧬 A milestone for biodiversity genomics. Project Psyche is building chromosome-level genomes for ~11,000 European butterflies & moths — 1,000 sequenced, 3,000+ collected, across 34 countries. 🔗 Read the publication: bit.ly/ProjectPsyche @projectpsyche.bsky.social #BiodiversityGenomics 🧬🌍

An interesting result is that the rate of species description has accelerated, with the largest numbers of new species per year in the past ~20 years. We're currently experiencing an age of discovery for Earth's biodiversity & the role of natural history museum collections couldn't be more important

Are you excited about pangenomics? If so, join us in Edinburgh on 8-9th June to discuss the latest methods & insights from using these approaches across biodiversity! More details here: royalsociety.org/science-even... Organised together with @henrylnorth.bsky.social & @joanameier.bsky.social!

The first of many exciting Erebia genomes associated with ERGA-CH 🦋🧬 Stay tuned !! @ergabiodiv.bsky.social

Are you interested in biodiversity genomics? Fantastic opportunity to join us as a Group Leader at the Tree of Life Programme, @sangerinstitute.bsky.social. 👇 sanger.wd103.myworkdayjobs.com/en-GB/Wellco...

Does obligate asexuality necessarily lead to genomic decay? We found that ancient asexual lineages of oribatid mites have static genomes, frozen in time, whereas genomes of sexual lineages seem to be expanding.
